<p>Dual-energy X-ray absorptiometry (DEXA) is rapidly gaining acceptance as a reference method for analysing body composition. Since initial developments in 2017, as part of the Advanced Livestock Measurement Technologies project, there has been an influx of DEXA measurements and some additional computed tomography (CT) measurements on genetically informative animals via the MLA funded Resource Flock and companion industry satellite flocks. Although more data is required, the results suggest that the DEXA lean meat yield is likely to be the same genetic trait as the CT measured lean meat yield. These results are promising and plans regarding the utilisation of DEXA data within Sheep Genetics national evaluation should begin. However, improving hook tracking technologies and data transfer pathways concurrently is also required.</p>
